In this commentary, the process performance of natural rubber processing wastewater systems was evaluated and compared. The key factors evaluated in here comprised the following: the type of wastewater, the prevention of system clogging by coagulated rubber, and the reduction of greenhouse gas (GHG) emissions. This commentary examined these variables in existing systems and in a pilot-scale rea...

A prototype endovascular electromechanical clot-extraction device was fabricated using a combination of shape memory polymer and shape memory nickel-titanium alloy (nitinol). Five embolic vascular occlusions were created in 4 rabbits by injecting thermally coagulated blood through a 4F catheter in the common carotid artery. Angiography immediately after clot injection showed complete or partial...

In connection with studies on riboflavin in various fractions of precancerous livers, the observation was made that homogenates of liver tissue from r a t s f e d m ' methylp dimethylaminoazobenzene failed to coagulate at 100 ~ C., whereas similar homogenates from normal rats coagulated completely in. 1 to 5 minutes. Accordingly a study was made of the stability towards heat of homogenates from...

Some representative quinones, viz. one naphthoquinone (plumbagin) and five anthraquinones (alizarin, purpurin, chrysazin, emodin, and anthrarufin), were subjected to electrocoagulation. It was found that the rate and extent of coagulation of these compounds appears to correlate with the number and relative position of their phenolic substituent groups, and that all of the coagulated quinones co...

We describe a simple technique of controlling air leakage from the lung parenchyma using BiClamp(®). The device creates appropriate protein coagulation at an air leakage point of the lung parenchyma. The leakage point and adjacent area are grasped with BiClamp(®) forceps and coagulated without tissue carbonization. After the procedure, no air leakage was recognized under airway pressure test of...

Adult laryngeal hemangiomas are rare and mainly involve the supraglottic region. Most common symptoms include dysphagia, dysphonia, shortness of breath and occasionally recurrent bleeding which sometimes cause a diagnostic dilemma for pulmonologists and head and neck surgeons. There is no consensus about the most appropriate treatment modality for laryngeal hemangiomas. We present a case of sup...

Microwave coagulation therapy (MCT) has been employed mainly for treatment of small size tumors. In the treatment, thin microwave antenna is inserted into the tumor and microwave energy heats up the tumor up to at least 60 degrees C for generation of enough coagulated volume including the target tumor. During the microwave radiation, reflection coefficient of treatment antenna changes significa...

are used in the treatment of burns, have not produced equally satisfactory results; and these are still under trial. The success of the tannic acid treatment as a first-aid dressing and as the routine treatment of burns is due to (?) The prevention of the absorption of the damaged tissues which are coagulated by tannic acid. (?) The formation of a crust, which supports and protects the tissues ...
